I am a Senior Research Scientist in Tencent AI Seattle Lab. My primary research interest lies in natural language processing and machine learning. Specifically, I am working on using knowledge (i.e., text retrieval, knowledge graph and etc) to enhance factuality and reasoning capibility of (large) language models.

I earned my Ph.D. in Computer Science and Engineering from the University of Notre Dame in 2023, advised by Prof. Meng Jiang. My research during Ph.D was generously supported by Bloomberg Ph.D Fellowship. Prior to my Ph.D., I received my Bachelor’s degree in Computer Science and Technology from Sichuan University in 2019.

I am actively seeking highly motivated interns who share my research interests. Kindly reach out to me at wyu1@nd.edu with your resume!
